This paper represents a new method for identifying the locations of multiple harmonic sources in power systems using independent component analysis and mutual information theory. Independent component analysis, which is a blind source separation technique, is applied for estimating the profiles of injected harmonic currents produced by harmonic sources. The mutual information theory has been applied for determining the exact location of harmonic sources. Numerical simulations were made to verify the accuracy of the proposed method in locating multiple harmonic sources in the test distribution systems. Results showed that the proposed method can accurately estimate the location of multiple harmonic sources without using the knowledge of many network parameters.
